Percutaneous intervention angioplasty

The radial artery has been used increasingly for percutaneous coronary intervention because of its safety and feasible access route. Nevertheless, transradial complications are possible because of the variation in radial artery anatomy. We experienced a case of the brachioradial artery injury secondary to catheterization, presenting as hypovolemic shock. A 76-year-old woman presented at our emergency department complaining of effort-induced angina. Coronary angiography via the right radial artery showed critical stenosis in the middle of the left anterior descending coronary artery...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become the standard treatment for severe aortic valve stenosis in patients at increased surgical risk. Percutaneous transfemoral (TF) is the access of choice due to its reduced invasiveness and perioperative morbidity/mortality compared with the trans-axillary, aortic, and apical routes. On the other hand, vascular access complications (VACs) of the TF access are associated with prolonged hospitalization, 30-day, and 1-year mortality...

PURPOSE: To assess the feasibility and efficacy of percutaneous transluminal renal angioplasty (PTRA) for pediatric renovascular hypertension (RVH) secondary to total renal artery occlusion (RAO). METHODS: From 2011 to 2021, 13 pediatric patients with RVH confirmed with 14 occluded renal artery lesions were reviewed. The mean age was11.2 years (range 4 to 16). Nine lesions involved main artery occlusion, while five lesions featured branch occlusion. Blood Pressure Ratio (BPR) was defined as the ratio of the actual BP value to the 95th percentile value adjusted for age, gender, and height...

Coronary artery stent infection (CSI) is one of the rarest complications associated with the percutaneous coronary intervention (PCI), usually requiring surgical intervention. Reaching and confirming the diagnosis remains the most challenging aspect of this complication. We describe a case of drug-eluting stents (DES) infection after several repeated procedures of primary angioplasty and stent implantation in the context of myocardial infarction. In the current era of growth of coronary stent implantation, it's important for clinicians to consider and to prevent such potentially fatal events...

BACKGROUND: In-stent restenosis (ISR) has become a significant obstacle to interventional therapy for atherosclerotic cardiovascular disease. The optimal percutaneous coronary intervention (PCI) strategy for patients with coronary ISR remains controversial. This network meta-analysis (NMA) was aimed to compare and estimate the effectiveness of different PCI strategies and commercial devices for the treatment of patients with coronary ISR. METHODS: In present study, we systematically searched PubMed, Embase, Web of Science, and Cochrane Library from database inception to October 20, 2022, to identify randomized controlled trials...

Transplant renal artery stenosis is the most common vascular complication that turns out following kidney transplantation and can lead to graft dysfunction and even its loss. The present report, describes A patient with end-stage renal disease who underwent living related renal transplantation. He had oliguria and creatinine rise in the post-operative course but all doppler ultrasonography (DUS) during the 2 months post-operation for the renal graft showed a normal mean resistive index in the graft renal artery...

Coronary sinus (CS) anomalies, although infrequent, are increasingly diagnosed with advances in interventional procedures and imaging techniques. Most cases are asymptomatic and incidentally diagnosed. We present a case of an elderly male without comorbidities who presented with acute angina. Coronary catheterisation revealed a double-vessel disease, but incidentally, sequential angiograms captured contrast filling in the levophase of CS, revealing a giant CS. Primary percutaneous angioplasty of the right coronary artery was performed successfully...

OBJECTIVES: Manual compression (MC) or vascular closure devices (VCDs) are used to achieve hemostasis after percutaneous transluminal angioplasty (PTA). However, limited data on the comparative safety and effectiveness of VCDs vs MC in patients with end-stage renal disease (ESRD) undergoing PTA are available. Accordingly, this study compared the safety and effectiveness of VCD and MC in patients with ESRD undergoing PTA. METHODS: This single-center retrospective cohort study included the data of patients with ESRD undergoing peripheral intervention at Chang Gung Memorial Hospital, Taiwan, from January 1, 2019, to June 30, 2022...

BACKGROUND: External iliac artery endofibrosis (EIAE) is a rare vascular disease which has been traditionally seen in avid cyclists. The conventional approach has been surgery, although no high-quality evidence suggests superiority of surgery over percutaneous endovascular intervention. There are limited data on the efficacy of stenting in EIAE. METHODS: Over a 14-year period, we treated 10 patients (13 limbs) with EIAE with stents. These patients had declined surgery...

BACKGROUND: Diabetes may be associated with differential outcomes in patients undergoing left main coronary revascularization with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). The aim of this study was to investigate outcomes in patients with left main disease with and without diabetes undergoing PCI versus CABG. METHODS: Individual patient data were pooled from 4 trials (SYNTAX [TAXUS Drug-Eluting Stent Versus Coronary Artery Bypass Surgery for the Treatment of Narrowed Arteries], PRECOMBAT [Bypass Surgery Versus Angioplasty Using Sirolimus-Eluting Stent in Patients With Left Main Coronary Artery Disease], NOBLE [PCI vs...

A rare form of large vessel vasculitis, Takayasu arteritis (TA) typically affects the aorta and its primary branches and rarely involves the coronary arteries. We present a case study of a female patient who had refractory hypertension and coronary artery disease for which she underwent percutaneous transluminal angioplasty. Subsequently, she was diagnosed with Takayasu arteritis. We wish to underscore the significance of timely identification and intervention as pivotal factors in improving patient outcomes and optimizing the effectiveness of therapeutic strategies in managing TA...

IMPORTANCE: Drug-coated balloons offer a potentially beneficial treatment strategy for the management of coronary in-stent restenosis. However, none have been previously evaluated or approved for use in coronary circulation in the United States. OBJECTIVE: To evaluate whether a paclitaxel-coated balloon is superior to an uncoated balloon in patients with in-stent restenosis undergoing percutaneous coronary intervention. DESIGN, SETTING, AND PARTICIPANTS: AGENT IDE, a multicenter randomized clinical trial, enrolled 600 patients with in-stent restenosis (lesion length <26 mm and reference vessel diameter >2...

A 63-year-old woman with uncontrolled hypertension despite taking 5 antihypertensive medications was referred for percutaneous renal artery intervention.

AIMS: The aims of this study were to examine the variability in research culture in busy cath labs in the APAC region and to propose a roadmap for hospitals to develop in-house research capabilities in conjunction with industry and academia. METHODS: Data related to research practices in the APAC region were collected from busy cath labs (at least 250 angioplasty/year) and analysed...

A 52-year-old man with a history of percutaneous coronary intervention (PCI) in the left anterior descending (LAD) coronary artery was admitted for a facilitated PCI following an anterior ST-elevation myocardial infarction treated with thrombolysis at a nearby clinic.

Limited data exist regarding drug-coated balloon (DCB) treatment in de novo large coronary arteries. We sought to demonstrate procedural characteristics, residual stenosis, and clinical outcomes following DCB angioplasty for de novo lesions in large versus small coronary arteries. The study included 184 consecutive patients with 223 de novo coronary lesions undergoing paclitaxel DCB angioplasty between January 2019 and August 2020, who were divided according to whether the DCB diameter was ≥ 3...

BACKGROUND: Percutaneous coronary interventions in heavily calcified coronary lesions are associated with technical difficulties and the worse prognosis. Lesion preparation is important to reduce complications and improve outcomes. The aim of this study is to compare the results of rotational atherectomy (RA) and intravascular lithotripsy (IVL) at achieving optimal stent implantation using intravascular ultrasound criteria. METHODS: Retrospective, single-center study comparing patients with heavily calcified coronary lesions that underwent percutaneous coronary interventions using RA or IVL...
